Our Medical Tags are made of non-magnetic/surgical stainless steel. These tags are 2″ x 1-1/8″ and are too thick to be bent with your fingers. The text is engraved on the tags, not embossed or stamped. Each tag comes with a 24″ steel ball chain (not the chain currently pictured on the site). The front side has Medical Graphic (caduceus) and the stock medical alert text shown in the example graphic. The back side has any text you enter in the fields – up to 5 lines. These are very high quality tags.
